I am trying to mesh a complex 3D geometry with a helical tube inside a cylindrical cavity with gambit 2.4.6; I split the volumes and made sure that the geometry is clean. I meshed the tube with hex/wedge elements with spacing 1 and was trying to mesh the outer volume (that of cylinder minus the tube) with TET mesh with spacing 1. And I encounter the error: "Unable to locate xxxxxx bytes of memory. The volume could not be meshed."

I know not many people use Gambit now but it'd be really helpful if some Gambit veteran could help me out here.

Things I tried:

>> Coarsen the mesh but encountered skewed elements.
>> Read somewhere that resetting the number of UNDO levels to zero might help. Tried that but no difference.
>> Read that running the journal file without displaying the graphics reduces the memory requirement but was unable to execute that. How to turn off the graphics and let the journal file run?

Some help would be really appreciated.
Thank you!

Use Size function to refine the area where you get skewed elements.

Thank you Max for the reply and apologies for the delayed response.
I did try that but was unable to use size function properly as the edge at which the size function was applied was a part of multiple volumes. I have switched to Ansys and was able to control mesh in a more efficient manner.

Thanks again for your time.
Good Day!

Then you needed to apply SF as much as your number of volumes
